Feature description
Second Level Call Forward No Answer enhances Flexible Call Forward
No Answer by forwarding unanswered calls twice. The following example
best illustrates this enhancement.
Party A places a call to extension 5000, which does not answer. Extension
5000 has Call Forward No Answer (CFNA) allowed and extension 6000
defined as its CFNA number. The call forwards to extension 6000. This is
the first level CFNA.
Extension 6000 also does not answer the call. This telephone has a Call
Forward No Answer and Second Level Call Forward No Answer allowed
Class of Service (FNA and SFA). As it has a CFNA number of 7000,
it forwards there. This is the second level of Call Forward No Answer.
Note that the forwarding DN is always obtained from the currently ringing
telephone.
If extension 7000 does not answer the call, one of two things may occur:

If the original call is a Direct Inward Dialing (DID) or internal call, the
forwarded call continues to ring until answered or the calling party
disconnects.
